Safety
The high voltage interference pulse can contain a very large quantity of energy and every precaution shall be taken to avoid
contact with EUT during a test. It is highly recommended that at least one other person is present (or very close by) during
the test.
Test Configuration
EUT Setup
The EUT shall be setup in a typical system configuration on an isolated wooden bench with NO GROUNDPLANE. The
power to the EUT and auxiliary equipment shall be from 12V or 24V sealed lead-acid batteries via a suitable fuse. The
length of the EUT power cable shall be no more than 2m. Any screens within the system shall be terminated at the battery

Inter-ship channels are for communications between ship stations. Inter-ship communications should be restricted to
Channels 6, 8, 72 and 77. If these are not available, the other channels marked for Inter-ship may be used.
Channel 70 is used exclusively for Digital Selective Calling (DSC) and is not available for regular voice
communications.
Notes:
1. Channel 06 may also be used for communications between ship stations and aircraft engaged in coordinated search and
rescue operations. Ship stations should avoid harmful interference to such communications on channel 06 as well as to
communications between aircraft stations, ice breakers and assisted ships during ice seasons.
2. Within the European Maritime Area and in Canada, channels 10, 67 and 73 may also be used by the individual admini
strations concerned for communication between ship stations, aircraft stations and participating land stations engaged
in coordinated search and rescue and anti-pollution operations in local areas. Channels 10 or 73 (depending on location)
are also used for the broadcast of Marine Safety Information by the Maritime and Coast Guard Agency in the UK only.
3. Channel 13 is designated for use on a worldwide basis as a navigation safety communication channel, primarily for
inter-ship navigation safety communications.
4. Channels 15 and 17 may also be used for on-board communications provided the effective radiated power does not
exceed 1 Watt.
5. The use of Channels 75 and 76 should be restricted to navigation related communication only and all precautions
should be taken to avoid harmful interference to channel 16. Transmit power is limited to 1 Watt.

Notes:
1. The letter “A” following a channel number indicates simplex use of the ship station transmit side of an international
semi-duplex channel. Operations are different from that of international operations on that channel.
2. Channel 13 should be used to contact a ship when there is danger of collision. All ships of length 20 meters or greater
are required to guard VHF channel 13, in addition to VHF channel 16, when operating within U.S. territorial waters.
3. Channel is Receive Only.
4. Channel 16 is used for calling other stations or for distress alerting.
5. Output power is fixed at 1 watt only.
6. Output power is initially set to 1 watt. User can temporarily override this restriction to transmit at high power.
